Porsche Coding using PIWIS Development Mode

Obd2tool.com here provides some coding procedures using Porsche Piwis Tester.

To code you need to be in development (E) mode, which is unfortunately in German. I’ve made a start at doing some translations courtesy of Google Translate below.

How to Enable OEM Porsche tester iii Developer Mode?

If you play around in simulation mode, the car it uses is a 991 coupe. Whilst not exactly the same as the 981, it’s very close. It’s a good start at poking around the software to see where things are without having to be connected to the car.

Last Mode coding DIY

This is a Porsche PIWIS DIY to recode the car so that it keeps the last driving modes set. I used this primarily to ensure that start/stop initialises OFF each time I start the car rather than me having to push the button each time I start the car.

I don’t know what other modes it keeps for the next time your start the car. It seems to keep the last PASM and seat heating settings, but not SPORT or SPORT PLUS.

Note: Development mode is in German. English translations are after each step to show what you are doing.

I can’t take credit for the procedure. I won’t name who it was, but they know who they are, and thanks for the help.

If you are worried about doing this for the first time on your car, it’s the same in simulation mode, so have a practice here first. Being simulation mode, it won’t let you save it.

To make the coding changes, do the following.

Change the PIWIS mode to E (development)

Open the diagnostics for the car type, then make the following selections.

1. BKE (bedien und klimaeinheit)
operation and climate

2. Codierung Anpassungen
Coding adaptations

3. Manuelle Codierung ohne MCR Regeln (Entwicklung)
Manual coding without MCR rules (development)

4. Select both kodierwert:kodierwert default fahrzustand and kodierwert:kodierwert default fahrzustand last mode
codeword default driving state

5. In Wert (value) dropdown
Change …fahrzustand to “last mode”
Change …fahrzustand last mode to “ja”

6. Click schreiben (save) at bottom.

Coding complete. Exit and change the settings back to V (aftersales) mode if desired.
